Swapped from a TBI to a Edelbrock carb.

Just looked at my Chiltons manual and it says ALL V8's starting in '87 have fuel pressure ranging from 35-47 depending on engine. For a '87 454 it says 34-46PSI.

It does have a little footnote number beside it( a 9 with a circle around it), but when you look down to see what it means it says "Carburetted: 5.0". Can't figure out why it would have that footnote beside a spec. line for a 454, LOL. It has the same footnote on all V8's( 305, 350 & 454).

On yours, was it originally TBI? What year?

THANKS!!!
